What is ModelAndView?

Comment

ModelAndView is a holder for both Model and View in the web MVC framework. These two classes are distinct; ModelAndView merely holds both to make it possible for a controller to return both model and view in a single return value. The view is resolved by a ViewResolver object; the model is data stored in a Map .Sep 22, 2565 BE

@Controller
public class MyController {

    @GetMapping(value = "/")
    public String home() {

        return "index";
    }

    @GetMapping(value = "/show")
    public ModelAndView show() {

        var mav = new ModelAndView();

        var now = LocalDateTime.now();
        var formatter = DateTimeFormatter.ISO_DATE_TIME;
        var dateTimeFormatted = formatter.format(now);

        mav.addObject("now", dateTimeFormatted);
        mav.setViewName("show");

        return mav;
    }
}
